Therefore, the sand removing operation can be simplified, the operation automation is high, and the labor cost is effectively reduced.
The following describes the sand mold 3D printing work box with reference to specific embodiments to further understand the inventive concept of the sand mold 3D printing work box. Referring to fig. 1 to 5, in an embodiment, a sand mold 3D printing work box 10 includes: the box body mechanism 100 comprises a mother board 110 and a daughter board 120 which are movably overlapped with each other, and the mother board 110 and the daughter board 120 are both provided with a plurality of launders 130; and the transmission mechanism 200 is movably connected with the daughter board 120 and is used for controlling the daughter board 120 to move relative to the motherboard 110.
Specifically, referring to fig. 2 and fig. 3, the motherboard 110 is movably disposed on the top of the daughter board 120, the motherboard 110 and the daughter board 120 may be two supporting boards with the same or different sizes, and further, the cross sections of the motherboard 110 and the daughter board 120 may be the same or different, and in this embodiment, no specific limitation is imposed, and only the motherboard 110 and the daughter board 120 are required to be disposed on top of each other. Wherein, the mother board bears the sand mould (sand core), before the sand cleaning, a plurality of gravity flow slots of the mother board 110 and a plurality of gravity flow slots of the daughter board 120 are staggered with each other, so that the sand mould (sand core) residual sand on the mother board 110 can not flow down from the gravity flow slots; when sand cleaning is started, the daughter board 120 slides relative to the mother board 110 through control, so that the staggered gravity flow grooves of the mother board 110 and the staggered gravity flow grooves of the daughter board 120 are aligned with each other, the mother board 110 and the daughter board 120 are in a screen shape, and residual sand on the mother board 110 flows down from the aligned gravity flow grooves. In this way, the self-flowing groove 130 is formed in the mother plate 110 and the daughter plate 120 of the box body mechanism 100, and the mother plate 110 and the daughter plate 120 can move relatively, so that the alignment state of the self-flowing groove and the daughter plate is changed, residual sand in the box body mechanism 100 can be cleaned in time as required, and the sand cleaning work efficiency is effectively improved. The self-flowing groove formed in the motherboard 110 and the daughter board 120 is a through hole formed therethrough. In one embodiment, the gravity flow groove 130 is an elongated through hole. It should be noted that the free-flow groove 130 may also include through holes with other cross-sectional shapes, and is not particularly limited in this embodiment.
Further, the transmission mechanism 200 is a mechanical driving mechanism for controlling the daughter board 120 to move relative to the mother board, so as to change the relative position of the daughter board 120 and the self-draining groove of the mother board 110, and then control the sand removal. In one embodiment, the transmission mechanism 200 includes a motor drive or a cylinder drive. Specifically, the daughter board is driven and connected by a motor driving part or a cylinder driving part, when the motor or the cylinder is started, the corresponding connecting part of the transmission mechanism 200 is moved, so that the daughter board connected with the transmission mechanism is driven to move. It should be noted that the driving mechanism 200 drives the daughter board 120 to move along the motherboard 110 in the horizontal direction, so that the two daughter boards can be misaligned or aligned with each other from the flow slots. In other embodiments, the transmission mechanism 200 may be in a non-direct connection state with the sub-plate 120 before the sand cleaning operation, and when the sand cleaning operation is required, the transmission mechanism may be in contact connection with the sub-plate 120 by performing a corresponding action, so as to control the movement of the sub-plate 120.
Above-mentioned sand mould 3D prints work box, mother board 110 and daughter board 120 through the stack setting, and a plurality of flowing groove 130 of flowing certainly have been seted up at mother board 110 and daughter board 120 respectively, further adopt drive mechanism 200 control connection daughter board 120, when needs sand removal, move along the horizontal direction through control daughter board 120, thereby make daughter board 120 and mother board 110 flow groove of flowing certainly change into the alignment state by original dislocation state, thereby make the remaining sand in the sand mould 3D prints the work box flow by flowing certainly, thereby play automatic effective sand removal effect, and need not to carry out the sand removal through the bottom plate that complicated operation pulling whole 3D printed the work box. Therefore, the sand removing operation can be simplified, the operation automation is high, and the labor cost is effectively reduced.
In order to stably support and mount the motherboard and the daughter board, in an embodiment, referring to fig. 2 and fig. 3, the box mechanism further includes a box 140, and the motherboard 110 and the daughter board 120 are accommodated in the box 140. Specifically, the motherboard 110 and the daughter board 120 are stacked in the box and disposed close to the bottom plate. In order to facilitate the flexible control of the daughter board relative to the mother board by the transmission mechanism, further, a bottom plate 150 having communication holes is further disposed at the bottom of the box body 140, and each of the overflow slots 130 is communicated with the communication holes. Thus, when the gravity flow grooves of the daughter board and the mother board are aligned with each other to start shakeout, the shakeout can flow out towards the communication hole position of the bottom board through the gravity flow grooves. The communication hole may be a rectangular through hole or a through hole of another shape, and is not particularly limited in this embodiment. It should be understood that, since the bottom plate is fixed in position, in order to facilitate the actuator to control the daughter board on the bottom plate to move in the horizontal direction, the daughter board needs to be communicated with the actuator through the bottom plate 150, and at this time, the bottom plate 150 needs to be perforated so that the actuator extends into the upper portion of the bottom plate through the communication hole to control the connection with the daughter board 120. It should be noted that the control connection manner between the daughter board 120 and the actuator 200 may be a contact connection or a direct mechanical connection, and is specifically determined by different types of actuators. Further, the daughter board 120 is slidably coupled to the backplane board 150. That is, the daughter board 120 is movable relative to the backplane 150 to enable relative movement of the daughter board 120 and the motherboard 110. For example, a plurality of rollers 160 are disposed between the sub-board 120 and the base plate 150. Specifically, the rollers 160 are linearly arranged in two rows. Thus, when the sub-board 110 moves left and right, the roller linearly moves on the base plate 150. It should be understood that the sand molds are housed in the case 140 after printing is completed, and are carried on the mother board and the daughter board on the base board. In one embodiment, the bottom plate 150 is fixedly disposed at the bottom of the case. That is, the bottom plate is provided integrally with the case.
In order to ensure that the relative positions of the motherboard and the daughter board are fixed, in an embodiment, referring to fig. 2, the motherboard 110 is provided with a plurality of guide rails 111, one surface of the daughter board 120 facing the motherboard 110 is provided with a plurality of sliding grooves 121, and each guide rail 111 is correspondingly slidably disposed in one of the sliding grooves 121. The installation length direction of the guide rail 111 and the slide groove 121 is perpendicular to the moving direction of the daughter board 120. For example, the guide rail 111 is a bar-shaped slider, and the sliding groove 121 does not correspond to a bar-shaped sliding groove. When the daughter board 120 moves towards one end along the horizontal direction, the guide rail of the mother board 110 slides out of the chute corresponding to the daughter board 120, and finally slides into the chute at another position after the daughter board stops moving, so that the positions of the daughter board 120 and the mother board 110 are kept relatively fixed, and the influence on free flowing of residual sand through the self-chute is avoided.
In order to further ensure that the daughter board can flexibly and stably move relative to the base board, in a preferred embodiment, referring to fig. 2, a flange 112 is disposed on a periphery of the mother board 110, and the flange 112 is fastened to the daughter board 120 and abuts against a surface of the base board 150 facing the daughter board. In this way, the flange 112 is provided at the periphery of the motherboard 110, and the flange is directly abutted to the bottom plate 150, so that a supporting effect can be achieved, and the rolling effect of the roller 160 provided between the daughter board 120 and the bottom plate 150 can be prevented from being affected by pressure, thereby ensuring that the daughter board 120 can flexibly and stably move along the bottom plate 150. In order to ensure that the guide rail of the mother board can smoothly slide from one sliding slot to the other sliding slot of the daughter board during the movement of the daughter board, the height of the folded edge 112 is further greater than the sum of the thickness of the daughter board 120 and the diameter of the roller 160. That is, the anchor clamps that set up between hem 112 and the mother board are greater than 90 degrees, make the daughter board when moving like this, and when the guide rail roll-off of mother board corresponds in the spout, have certain margin at the direction of height and make the mother board wholly raise to be convenient for the guide rail slides smoothly and enters into another spout internal fixation. In a preferred embodiment, a sealing felt is arranged between the side of the mother plate and the side wall of the box body. Thus, the residual sand in the sand box can not flow out through the side edge of the mother plate.
In order to achieve the effect that the transmission mechanism effectively controls the daughter board to move relative to the motherboard, in an embodiment, referring to fig. 4, the transmission mechanism 200 includes a screw transmission member 210 and an air cylinder transmission member 220 connected to each other, the air cylinder transmission member 220 is connected to the daughter board 120 in a controlled manner, and the screw transmission member 210 drives the air cylinder transmission member 220 to move in a horizontal direction, so as to control the daughter board 120 and the motherboard 110 to move in a staggered manner. That is, the sub-board 120 is controlled and connected by the cylinder transmission member 220, and the screw transmission member 210 moves in the horizontal direction by driving the cylinder transmission member 220, so that the cylinder transmission member 220 controls the connected sub-board 120 to move in the super-horizontal direction. More specifically, the screw driver 210 extends into the upper portion of the bottom plate through the communication hole of the bottom plate 150 to be connected to the sub-board 120. It should be noted that the manner of controlling the connection of the daughter board 120 by the cylinder actuator 220 may be a mechanical direct connection relationship, or may be a connection by a contact connection manner, which is specifically determined by the cylinder actuator 220.
In an embodiment, referring to fig. 5, the screw transmission member 210 includes a connecting seat 211, a screw 212, a nut 213, a driver 214 and a connecting member 215, the screw 212 is fixedly installed on the connecting seat 211, the nut 213 is connected to the screw 212, the driver 214 is connected to the connecting seat 211 and the screw 212, the connecting member 215 is fixedly connected to the nut 213, and the connecting member 215 is connected to the cylinder transmission member 220. Specifically, when the driver 214 is activated, the screw rod 212 is driven to rotate, so that the nut 213 moves towards one end of the screw rod, and then the connecting member 215 connected to the nut is driven to move, so as to drive the cylinder transmission member 220 connected to the connecting member to move towards one end of the screw rod.
In an embodiment, please refer to fig. 5, the cylinder transmission 220 includes a bracket 221, a cylinder 222, a cylinder guide rod 223, a rotating shaft 224, a connecting rod 225, a rotating sleeve 226, a fixing sleeve 227 and a guide rod 228, the guide rod 228 is movably connected with the fixing sleeve 227, the fixing sleeve 227 is fixedly disposed at two ends of the connecting member 215, the cylinder 222 is fixedly mounted on the bracket 221, the bracket 221 is fixed at the bottom of the connecting member 215, and the cylinder guide rod 223 is sequentially connected with the rotating shaft 224, the connecting rod 225, the rotating sleeve 226 and the fixing sleeve 227. Specifically, two ends of the bracket 221 are bent structures, one end of the bracket 215 is fixedly disposed at the bottom of the connecting member 215, and the other end of the bracket 215 is provided with the cylinder 222. The top of the cylinder 222 is provided with a cylinder guide rod 223, one end of the cylinder guide rod 223 far away from the cylinder is provided with a rotating shaft 224, the rotating shaft is rotatably provided with two groups of bendable connecting rods 225, two ends of the connecting piece are respectively provided with two groups of rotating sleeves 226 and a fixed sleeve 227, the connecting rod 225 is arranged between the rotating shaft 224 and the rotating sleeves, the connecting rod 225 is arranged between the rotating sleeves 226 and the fixed sleeve 227, and the fixed sleeve 227 is also provided with a guide rod 228. It should be understood that since two sets of rotating and fixing sleeves 226 and 227 are provided at both ends of the connecting member, respectively, the corresponding connecting rod 225 and guide rod 228 have two sets. Specifically, when the cylinder is activated, the cylinder guide 223 contracts, pulling the take-up link 225 downward, which in turn causes the two sets of oppositely disposed guide rods 228 to contract toward each other. In a preferred embodiment, the bottom of the sub-plate 120 is provided with a stopper 122, and the cylinder actuator 220 movably grips the stopper 122. Further, the guide rod 228 is movable to grasp the stopper 122. It should be noted that, in a normal state, the two groups of guide rods 228 are far away from each other and do not contact with the stopper when the cylinder is stopped, after the cylinder is started, under the pulling and holding action of the guide rods of the cylinder, the two groups of guide rods 228 are close to each other and contract to form a grabbing and grabbing structure, and when the cylinder is gradually close to each other, the two groups of guide rods are finally stably grabbed and fixed on two sides of the stopper due to the arrangement of the stopper. Thus, when the driver 214 of the lead screw transmission member is started, the connecting member 215 connected to the cylinder transmission 220 is moved toward the horizontal direction, so as to drive the guide rod 228 of the cylinder transmission 220 to move toward the horizontal direction, thereby further realizing that the stopper arranged on the daughter board drives the daughter board to move toward the horizontal direction under the grabbing fixation of the guide rod 228.
In order to facilitate timely and effective recovery of the residual sand falling from the chute, in an embodiment, please refer to fig. 1, the sand mold 3D printing work box further includes a sand cleaning mechanism 300, the sand cleaning mechanism 300 includes a sand hopper 310, a sand suction structure 320 and a recovery structure 330, the sand hopper 310 is disposed near the daughter board 120, the sand suction structure 320 is communicated with the sand hopper 310, and the recovery structure 330 is connected with the sand suction structure 320.

Particularly, the sand hopper 310 is arranged close to the daughter board 120, so that residual sand flowing out of the flow groove through the daughter board and the mother board can be effectively stored in time. For example, the sand hopper 310 is fixedly installed at a lower portion of the sub-plate 120. This facilitates the automatic dropping of the remaining sand into the sand hopper 310 according to the principle of gravity. For example, the sand suction structure includes an industrial vacuum cleaner. The industrial cleaner may be an Italian KEVAC cleaner, model KB5S, among others. For the working principle and process of the sand sucking structure sucking the residual sand in the sand hopper 310 to the recycling structure 330, reference may be made to the working principle and process of the industrial vacuum cleaner of the above type, which is not described herein in detail. In order to ensure that shakeout falling from the launder into the sand hopper affects the operation of the transmission mechanism, in a preferred embodiment a first seal guard is provided between the sand hopper 310 and the conveyor mechanism 200. For example, the first seal guard is a protective cover that covers the transfer mechanism 200. It should be understood that, because the transmission mechanism is tightly connected with the daughter board, the shakeout hopper arranged close to the daughter board inevitably contacts with the transmission mechanism, and therefore, through the arrangement of the protective cover, the shakeout hopper is favorably and effectively prevented from flowing into the transmission mechanism, so that the work of the transmission mechanism is influenced. In a preferred embodiment, the number of the sand hoppers 310 is several, and each sand hopper is arranged corresponding to one or several gravity flow grooves, so that sand can be collected conveniently and effectively in time.

During specific operation, the jacking mechanism can be selectively started according to actual work, namely the jacking mechanism can be matched with the transmission mechanism to work together in the sand removal work, also can not be matched to start, and only can be installed as a support piece.
In order to stably mount the transmission mechanism, in one embodiment, the transmission mechanism 200 is connected to the jacking mechanism 400. Specifically, the transmission mechanism 200 is connected to a fixed portion of the jacking mechanism 400. Namely, the transmission mechanism 200 is supported and arranged by the fixing part of the jacking mechanism 400.

It is emphasized that the daughter board moves along the horizontal direction, so that the daughter board and the mother board are always in a mutually overlapped state, and only the positions of the daughter board and the mother board in the horizontal direction are subjected to relative displacement change.
S130: the self-flow grooves of the daughter board and the mother board are staggered with each other to start sand flowing;
the daughter board moves through the transmission mechanism, so that the relative position of the mother board and the self-flowing groove of the daughter board is changed, wherein the fact that the transmission mechanism controls the horizontal movement of the daughter board is that the self-flowing grooves of the mother board and the daughter board are completely aligned with each other is emphasized, and therefore the residual sand can flow out of the work box mechanism at the maximum speed.
S140: and after the sand flowing is finished, the transmission mechanism is reset.
Namely, after the residual sand of the tool box mechanism completely flows out, the transmission mechanism is reset to work and drive the daughter board to move towards the opposite direction until the initial position state of the daughter board and the mother board is recovered.
